Garmins G1000 panel dominates

the newairplane market

The promise is greater functionality at lower cost. Better maintainability and reliability than analog instrumentation? Not just data, but information.

The G1000 is a integrated

system of communicatingmodules.

Service is primarily swappingLRUs and repairing them in-

house or back at Garmin.

The various LRUs are commonto many different airframesfrom the C172 to VLJs.

Im familiar with the C172Sconfiguration, so Illconcentrate on that.

Its modular

In the G1000 flight data are measured by remote sensors

and displayed on the PFD.

In addition we have an altitude bug and a 6-second trend vector.

The altitude bug is notintegrated with theKAP140 autopilot. Ithas to be set

independently.

In theC172S/G1000/KAP140,there are threealtimeters to set!

Garmin has recentlyintroduced its ownintegrated autopilot.

The altimeter is set with the

outer knob of the OBS courseselector on the RH bezel.

The airspeed indicator is also replaced with a tape.

TAS is computedautomatically.Vr, Vx, Vy bugs can beadjusted from thedefaults.

The AHRS will degrade into a reversionary mode if

external inputs are lost. It has some redundancy

Its all electrical except for three standby instruments

If a panel fails, the remaining panel can operate in reversionarymode.(Automatic or the red button.)

In reversionary mode, the PFD display adds engine instrumentation.

Normally, engine data only shows on the MFD.

In the C172/Garmin 1000 a standby battery can power the essential bus.

Essentialbus powers PFD, AHRS, engine/airframesensors, #1 Nav-Com and 1 GPS.

If the alternator fails, turning off the master switch andleaving the stand-by battery switch armedwill allow

you to preserve main battery capacity for later in theflight.

The standby battery has little or no power remainingonce the essential bus voltage drops to 20V.

(excerpted from the C172S manual)

From the starting checklist:

4. STBY BATT Switch TEST (hold for 20 sec, verify thegreen test lamp does not go out), then ARM (verify PFDcomes on)

checks the condition of the standby battery.

The GPS interface will be familiar to Garmin 430/530 users.

Curiously, the direct/direct shortcut for activating a flight plan

leg is absent on the G1000.

You can still useactivate legvia themenukey, or onthe MFD only, usethe act-legsoft-key.

The King School is a good overview -- but is $249

The Garmin simulators are faithful and essential

Harder to fly than the 430/530 simulators IMODual screens add realism.

FS X supposedly has a partial simulation.

If youve not flown a glass panel, give it a try.

I found the instrument display intuitive easy to transition to.

Practice with the simulator was greatly rewarded.

The GPS is easy if you know the 430/530.

Keep looking out the window!!
